Multifunctional phosphine stabilized gold nanoparticles: an active catalytic system for three-component coupling reaction.

Bibek Jyoti Borah et al.

Journal of nanoscience and nanotechnology, 13(7), 5080-5087 (2013-08-02)

Multifunctional phosphine based ligands, 1,1,1-tris(diphenylphosphinomethyl)ethane [CH3C(CH2 PPh2)3][P3] and 1,1,1-tris(diphenylphosphinomethyl)ethane trisulphide [CH3C(CH2P(S)Ph2)3][P3S3] have been introduced to stabilize Au(o)-nanoparticles having small core diameter and narrow size distribution. The Au(o)-nanoparticles were synthesized by the reduction of HAuCl4 precursor with NaBH4 in the presence

Cytotoxicity and genotoxicity induced by photothermal effects of colloidal gold nanorods.

Young Joo Choi et al.

Journal of nanoscience and nanotechnology, 13(6), 4437-4445 (2013-07-19)

Gold nanorods (Au NRs) that absorb near-infrared (NIR) light have great potential in the field of nanomedicine. Photothermal therapy (PTT), a very attractive cancer therapy in nanomedicine, combines nanomaterials and light. The aim of this study was to elucidate the
